The question has already been answered earlier by The WikiAnswers Community. The main reason is to provide the customer with a variety of options in terms of strength, color and comfort. The answer that was submitted gave a very nice explanation:
"Each of the fiber has it's own properties - both (i) benefiting to end user and (ii) does not contribute to the performance expected by ed user. Few fibers have good strength but does not have comfort and warmth, e.g. synthetic fibers like polyester, nylon. Few fibers are very comfortable, warming, absorptive, but does not have good strength. e.g. Cottons or natural fibers. Blending of fiber allows to offer end user the properties expected in terms of strength, feel, comfort, warmth, absorption, thermal properties, etc. This also allows to manufacturer to utilise the fibers for their dye/colour uptake properties and offer customer / end user a wide range of choice for colours / prints."
Blending fibres can give you some of the properties of the components fibres and so improve the qualities of the fabric. For example, blends of cotton and polyester give the breathability of cotton with the low-creasing property of polyester.
the fibre elongating is the total elongation at the time of breakage of fibre while testing fibre properties.
